Nvidia's GeForce RTX 4070, a highly popular graphics card, might soon see a variant featuring slower GDDR6 VRAM instead of the high-speed GDDR6X. This potential shift comes amid reports of a significant shortage of Micron's GDDR6X VRAM, which is essential for Nvidia's current RTX 40-series lineup.

Current Supply Challenges

A recent report from a tech site in China highlights that the supply of Micron's GDDR6X VRAM is under strain. Micron is the exclusive supplier of GDDR6X memory, which powers Nvidia's RTX 4070, 4080, and 4090 cards, as well as their Super variants. While Micron also produces GDDR6, this type of VRAM is more widely available as it is manufactured by other companies like Samsung and SK Hynix, which helps keep its cost lower, although it is not as fast as GDDR6X.

Impact on Nvidia's Production

Nvidia's reliance on a single supplier for GDDR6X means that any disruption in the supply chain can significantly impact production. According to BenchLife.info, this is exactly what's happening now, with the RTX 4070 facing supply challenges. To meet the high demand, particularly in the Chinese market, Nvidia is reportedly considering releasing an RTX 4070 variant equipped with GDDR6 VRAM instead.

Technical Specifications and Performance

Currently, the RTX 4070 Founders Edition and all third-party models come with 12 GB of Micron GDDR6X, clocked at 21 GT/s. In comparison, Samsung mass-produces GDDR6 at 20 MT/s, and also offers 24 MT/s for sampling. If Nvidia were to use Samsung's 20 MT/s GDDR6, the RTX 4070 would experience a slight drop in total memory bandwidth—from 504 GB/s with GDDR6X to 480 GB/s with GDDR6—a reduction of just 5%.

Potential Price Reduction

The key question arising from this potential change is how it would affect the price of the RTX 4070. GDDR6 is more widely produced and used by companies like AMD, Intel, Microsoft, Nvidia, and Sony, which generally makes it cheaper than GDDR6X. While exact price differences are hard to determine due to the lack of spot price tracking for Micron's faster VRAM, it is estimated that using GDDR6 could lower the cost of the RTX 4070 by approximately $30 or more, given that the card uses six VRAM chips.

Market Implications

Should Nvidia proceed with this change, it might offer a more affordable RTX 4070 variant to consumers, especially in markets like China where demand is high. This move could also set a precedent for how Nvidia addresses future supply chain disruptions, potentially influencing their production strategies and pricing models.

Final Thoughts

The potential release of an RTX 4070 variant with GDDR6 VRAM highlights the complexities of modern GPU manufacturing and the impacts of supply chain issues. While the performance difference may be minimal, the cost savings could make the RTX 4070 more accessible to a broader range of gamers. As Nvidia navigates these challenges, the gaming community will be watching closely to see how these changes unfold and affect the market.
